get_realtime_webhook

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden of behavioral disclosure, yet it discloses nothing beyond what the verb 'Get' implies: a read operation. It does not describe the response shape, not-found behavior, authentication requirements, rate limits, or side-effect profile. The wording is nearly tautological with the tool name, adding only 'Kit' and 'details'.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is five words, one sentence, with zero filler, and the verb-resource pair is front-loaded. It is appropriately compact for a trivial single-resource fetch. It loses a point because the brevity comes at the expense of substance that other dimensions (usage guidance, behavioral context) needed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read with three required, fully schema-documented parameters and no nested objects, the description is minimally adequate. However, with no output schema and no annotations, the return shape ('details' content) and error behavior are left completely unspecified, which are real gaps an agent would face when interpreting the response.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% — account_id, app_id, and webhook_id each have meaningful schema descriptions — so the baseline of 3 applies. The description adds no parameter-level semantics (e.g., that the webhook belongs to the app within the account), but it does not need to compensate since the schema already documents every parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Get') and a specific resource ('Realtime Kit webhook'), which is unambiguous and distinguishes it from sibling getters in the same product family like get_realtime_livestream, get_realtime_meeting, and get_realtime_recording. The noun 'webhook' clearly differentiates it from list_realtime_webhooks by implying a single-item fetch. It stops short of 5 because it never explicitly states the single-item scope and 'details' is vague about what is actually returned.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance is provided. The description does not state conditions for choosing this over list_realtime_webhooks, nor any prerequisites or context (e.g., the webhook must belong to the specified app_id). Usage must be inferred entirely from the schema requiring a webhook_id and from the get-vs-list sibling naming convention, which is weak evidence at best.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
